ABSTRACT

The invention is a novel soybean cultivar designated M001483 with high yield potential, early Group 3 maturity, and excellent standability. The invention relates to seeds of the cultivar M001483, plants of the cultivar M001483, and to methods for producing a soybean plant by crossing of the cultivar M001483 by itself or another soybean genotype.

FIELD OF THE INVENTION

This invention is in the field of soybean breeding, specificallyrelating to a soybean cultivar designated M001483.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinctive soybean cultivar,designated M001483. There are numerous steps in the development of anynovel, desirable plant germplasm. Plant breeding begins with theanalysis and definition of problems and weaknesses of the currentgermplasm, the establishment of program goals, and the definition ofspecific breeding objectives. The next step is selection of germplasmthat possess the traits to meet the program goals. The goal is tocombine in a single variety an improved combination of desirable traitsfrom the parental germplasm. These important traits may include higherseed yield, resistance to diseases and insects, better stems and roots,tolerance to drought and heat, and better agronomic quality.

Choice of breeding or selection methods depends on the mode of plantreproduction, the heritability of the trait(s) being improved, and thetype of cultivar used commercially (e.g., F₁hybrid cultivar, purelinecultivar, etc.). For highly heritable traits, a choice of superiorindividual plants evaluated at a single location will be effective,whereas for traits with low heritability, selection should be based onmean values obtained from replicated evaluations of families of relatedplants. Popular selection methods commonly include pedigree selection,modified pedigree selection, mass selection, and recurrent selection.

The complexity of inheritance influences choice of the breeding method.Backcross breeding is used to transfer one or a few favorable genes fora highly heritable trait into a desirable cultivar. This approach hasbeen used extensively for breeding disease-resistant cultivars. Variousrecurrent selection techniques are used to improve quantitativelyinherited traits controlled by numerous genes. The use of recurrentselection in self-pollinating crops depends on the ease of pollination,the frequency of successful hybrids from each pollination, and thenumber of hybrid offspring from each successful cross.

Each breeding program should include a periodic, objective evaluation ofthe efficiency of the breeding procedure. Evaluation criteria varydepending on the goal and objectives, but should include gain fromselection per year based on comparisons to an appropriate standard,overall value of the advanced breeding lines, and number of successfulcultivars produced per unit of input (e.g., per year, per dollarexpended, etc.).

Promising advanced breeding lines are thoroughly tested and compared toappropriate standards in environments representative of the commercialtarget area(s) for three or more years. The best lines are candidatesfor new commercial cultivars; those still deficient in a few traits maybe used as parents to produce new populations for further selection.

These processes, which lead to the final step of marketing anddistribution, usually take from eight to 12 years from the time thefirst cross is made. Therefore, development of new cultivars is atime-consuming process that requires precise forward planning, efficientuse of resources, and a minimum of changes in direction.

A most difficult task is the identification of individuals that aregenetically superior, because for most traits the true genotypic valueis masked by other confounding plant traits or environmental factors.One method of identifying a superior plant is to observe its performancerelative to other experimental plants and to a widely grown standardcultivar. If a single observation is inconclusive, replicatedobservations provide a better estimate of its genetic worth.

The goal of a plant breeding is to develop new, unique and superiorsoybean cultivars and hybrids. The breeder initially selects and crossestwo or more parental lines, followed by repeated selfing and selection,producing many new genetic combinations. The breeder can theoreticallygenerate billions of different genetic combinations via crossing,selfing and mutations. The breeder has no direct control at the cellularlevel. Therefore, two breeders will never develop the same line, or evenvery similar lines, having the same soybean traits.

Each year, the plant breeder selects the germplasm to advance to thenext generation. This germplasm is grown under unique and differentgeographical, climate and soil conditions, and further selection arethen made, during and at the end of the growing season. The cultivarswhich are developed are unpredictable. This unpredictability is becausethe breeder's selection occurs in unique environments and with millionsof different possible genetic combinations being generated. A breeder ofordinary skill in the art cannot predict the final resulting lines hedevelops, except possibly in a very gross and general fashion. The samebreeder cannot produce the same cultivar twice by using the exact sameoriginal parents and the same selection techniques. Thisunpredictability results in the expenditure of large amounts of researchmonies to develop superior new soybean cultivars.

The development of new soybean cultivars requires the development andselection of soybean varieties, the crossing of these varieties andselection of superior hybrid crosses. The hybrid seed is produced bymanual crosses between selected male-fertile parents or by using malesterility systems. These hybrids are selected for certain single genetrains such as pod color, flower color, pubescence color or herbicideresistance which indicate that the seed was truly a hybrid. Additionaldata on parental lines as well as the phenotype of the hybrid influencethe breeder's decision to continue with the specific hybrid cross.

Pedigree breeding and recurrent selection breeding methods are used todevelop cultivars from breeding populations. Breeding programs combinedesirable traits from two or more cultivars or various broad-basedsources into breeding pools from which cultivars are developed byselfing and selection of desired phenotypes. The new cultivars areevaluated to determine which have commercial potential.

Pedigree breeding is used commonly for the improvement ofself-pollinating crops. Two parents which possess favorable,complementary traits are crossed to produce an F₁. An F₂ population isproduced by selfing one or several F1's. Selection of the bestindividuals may begin in the F₂ population; then, beginning in the F₃,the best individuals in the families are selected. Replicated testing offamilies can begin the F₄ generation to improve the effectiveness ofseletion for traits with low heritability. At an advanced stage ofinbreeding (i.e., F₆ and F₇), the best lines or mixtures ofphenotypically similar lines are tested for potential release as newcultivars.

Mass and recurrent selections can be used to improve populations ofeither self- or cross-pollinating crops. A genetically variablepopulation of heterozygous individuals is either identified or createdby intercrossing several different parents. The best plants are selectedbased on individual superiority, outstanding progeny, or excellentcombining ability. The selected plants are intercrossed to produce a newpopulation in which further cycles of selection are continued.

Backcross breeding has been used to transfer genes for a simplyinherited, highly heritable trait into a desirable homozygous cultivaror inbred line which is the recurrent parent. The source of the trait tobe transferred is called the donor parent. The resulting plant isexpected to have the attributes of the recurrent parent (e.g., cultivar)and the desirable trait transferred from the donor parent. After theinitial cross, individuals possessing the phenotype of the donor parentare selected and repeatedly crossed (backcrossed) to the recurrentparent. The resulting plant is expected to have the attributes of therecurrent parent (e.g., cultivar) and the desirable trait transferredfrom the donor parent.

The single-seed descent procedure in the strict sense refers to plantinga segregating population, harvesting a sample of one seed per plant, andusing the one-seed sample to plant the next generation. When thepopulation has been advanced from the F₂ to the desired level ofinbreeding, the plants from which lines are derived will each trace todifferent F₂, individuals. The number of plants in a population declineseach generation due to failure of some seeds to germinate or some plantsto produce at least one seed. As a result, not all of the F₂ plantsoriginally sampled in the population will be represented by a progenywhen generation advance is completed.

In a multiple-seed procedure, soybean breeders commonly harvest one ormore pods from each plant in a population and thresh them together toform a bulk. Part of the bulk is used to plant the next generation andpart is put in reserve. The procedure has been referred to as modifiedsingle-seed descent or the pod-bulk technique. The multiple-seedprocedure has been used to save labor at harvest. It is considerablyfaster to thresh pods with a machine than to remove one seed from eachby hand for the single-seed procedure. The multiple-seed procedure alsomakes it possible to plant the same number of seeds of a population eachgeneration of inbreeding. Enough seeds are harvested to make up forthose plants that did not germinate or produce seed.

Descriptions of other breeding methods that are commonly used fordifferent traits and crops can be found in several reference books(e.g., Allard, 1960; Simmonds, 1979; Sneep et al., 1979; Fehr, 1987, allincorporated herein by reference).

Proper testing should detect any major faults and establish the level ofsuperiority or improvement over current cultivars. In addition toshowing superior performance, there must be a demand for a new cultivarthat is compatible with industry standards or which creates a newmarket. The introduction of a new cultivar will incur additional coststo the seed producer, the grower, the processor and the consumer, forspecial advertising and marketing, altered seed and commercialproduction practices, and new product utilization. The testingproceeding release of a new cultivar should take into considerationresearch and development costs as well as technical superiority of thefinal cultivar. For seed-propagated cultivars, it must be feasible toproduce seed easily and economically.

Soybean, Glycine max (L), is an important and valuable field crop. Thus,a continuing goal of plant breeders is to develop stable, high yieldingsoybean cultivars that are agronomically sound. The reasons for thisgoal are obviously to maximize the amount of grain produced on the landused and to supply food for both animals and humans. To accomplish thisgoal, the soybean breeder must select and develop soybean plants thathave the traits that result in superior cultivars.

DETAILED DESCRIPTION OF THE INVENTION

M001483 was selected from an F6 plant from the cross, 13404×9273. 13404is an expermental line developed by Midwest Oilseeds. 9273 is acommercial cultivar marketed by Pioneer Hi-Bred International. The crosswas made at the Novartis Seeds, Inc. Research Center at Washington,Iowa, in July, 1993. The F1 and F2 generations were grown at theNovartis Seeds, Inc. Research Farm at Kekaha, Kauai, Hi., in the winterof 1993-94. The F3 generation was grown at Washington in the summer of1994, the F4 and F5 at Kekaha in the winter of 1994-95, and the F6 atthe Novartis Seeds, Inc. Research Center at Washington, Iowa in thesummer of 1995. Single plants were harvested and threshed individually.Each was tested in a preliminary yield trial at Washington, Iowa in1996. One of these, designated M001483, was selected for advancement toa second year retest in 1997 and was tested in advanced trials in thenorthern U.S. and Ontario in 1998. It was tested in the greenhouse atthe Novartis Seeds, Inc. Research Center at Bay, Ariz., for resistanceto Phytophthora sojae in 1997 and 1998 and found to be susceptible. Asoybean cultivar needs to be highly homogeneous, homozygous andreproducible to be useful as a commercial cultivar. There are manyanalytical methods available to determine the homozygotic and phenotypicstability of these varieties.

The oldest and most traditional method of analysis is the observation ofphenotypic traits. The data is usually collected in field experimentsover the life of the soybean plants to be examined. Phenotypiccharacteristics most often observed are for traits associated with seedyield, lodging resistance, disease resistance, emergence, maturity,plant height, shattering, flower color, pubescence color, pod color andhilum color.

In addition to phenotypic observations, the genotype of a plant can alsobe examined. There are many laboratory-based techniques available forthe analysis, comparison and characterization of plant genotype; amongthese are Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), and Simple SequenceRepeats (SSRs) which are also referred to as Microsatellites.

The cultivar of the invention has shown uniformity and stability for alltraits, as described in the following variety description information.It has been self-pollinated a sufficient number of generations, withcareful attention to uniformity of plant type to ensure homozygosity andphenotypic stability. The line has been increased with continuedobservation for uniformity. No variant traits have been observed or areexpected in M001483. Soybean cultivar M001483, being substantiallyhomozygous, can be reproduced by planting seeds of the line, growing theresulting soybean plants under self-pollinating or sib-pollinatingconditions, and harvesting the resulting seed, using techniques familiarto the agricultural arts.

Soybean cultivar M001483 has the following morphologic and othercharacteristics:

Plant Type: Intermediate Hypocotyl Length: Long Leaf Shape: Ovate StemTermination: Indeterminate Pubescence Color: Light Tawny Flower Color:White Pod Color: Tan Seed Hilum Color: Black Leaf Color: Medium GreenSeed Coat Color: Yellow Seed Cotyledon Color: Yellow Seed PeroxidaseActivity: High Phytophthora Res. Gene Susc. Maturity Group III RelativeMaturity III-2 Ave. Seeds per Pound 2900

The invention also encompasses plants of cultivar M001483 and partsthereof further comprising one or more specific, single gene transferredtraits. Such traits are introgressed into cultivar M001483 from anothersoybean cultivar or are directly transformed into cultivar M001483.Preferably, one or more new traits are transferred to cultivar M001483,or, alternatively, one or more traits of cultivar M001483 are altered orsubstituted. The introgression of the trait(s) into cultivar M001483 isfor example achieved by recurrent selection breeding, for example bybackcrossing. In this case, cultivar M001483 (the recurrent parent) isfirst crossed to a donor inbred (the non-recurrent parent) that carriesthe appropriate gene(s) for the trait(s) in question. The progeny ofthis cross is then mated back to the recurrent parent followed byselection in the resultant progeny for the desired trait(s) to betransferred from the non-recurrent parent. After three, preferably four,more preferably five or more generations of backcrosses with therecurrent parent with selection for the desired trait(s), the progenywill be heterozygous for loci controlling the trait(s) beingtransferred, but will be like the recurrent parent for most or almostall other genes (see, for example, Poehlman & Sleper (1995) BreedingField Crops, 4th Ed., 172-175; Fehr (1987) Principles of CultivarDevelopment, Vol. 1: Theory and Technique, 360-376, incorporated hereinby reference).

The laboratory-based techniques described above, in particular RFLP andSSR, can be used in such backcrosses to identify the progenies havingthe highest degree of genetic identity with the recurrent parent. Thispermits one to accelerate the production of soybean cultivars having atleast 90%, preferably at least 95%, more preferably at least 99% geneticidentity with the recurrent parent, yet more preferably geneticallyidentical to the recurrent parent, and further comprising the trait(s)introgressed from the donor patent. Such determination of geneticidentity can be based on molecular markers used in the laboratory-basedtechniques described above.

The last backcross generation is then selfed to give pure breedingprogeny for the gene(s) being transferred. The resulting plants haveessentially all of the morphological and physiological characteristicsof cultivar M001483, in addition to the single gene trait(s) transferredto the inbred. The exact backcrossing protocol will depend on the traitbeing altered to determine an appropriate testing protocol. Althoughbackcrossing methods are simplified when the trait being transferred isa dominant allele, a recessive allele may also be transferred. In thisinstance it may be necessary to introduce a test of the progeny todetermine if the desired trait has been successfully transferred.

The cultivar of the invention can also be used for transformation whereexogenous genes are introduced and expressed by the cultivar of theinvention. Genetic variants created either through traditional breedingmethods using cultivar M001483 or through transformation of cultivarM001483 by any of a number of protocols known to those of skill in theart are intended to be within the scope of this invention (see e.g.Trick et al. (1997) Recent advances in soybean transformation, in PlantTissue Culture and Biotechnology, 3:9-26, incorporated herein byreference).

Production of a genetically modified plant tissue by transformationcombines teachings of the present disclosure with a variety oftechniques and expedients known in the art. In most instances alternateexpedients exist for each stage of the overall process. The choice ofexpedients depends on the variables such as the plasmid vector systemchosen for the cloning and introduction of the desired recombinant DNAmolecule, as well as the particular structural gene, promoter elementsand upstream elements used. Persons skilled in the art are able toselect and use appropriate alternatives to achieve functionality.Culture conditions for expressing desired structural genes and culturedcells are known in the art. Also as known in the art, soybeans aretransformable and regenerable such that whole plants containing andexpressing desired genes under regulatory control may be obtained.General descriptions of plant expression vectors and reporter genes andtransformation protocols can be found in Gruber, et al., “Vectors forPlant Transformation, in Methods in Plant Molecular Biology &Biotechnology” in Glich et al., (Eds. pp. 89-119, CRC Press, 1993).Moreover GUS expression vectors and GUS gene cassettes are availablefrom Clone Tech Laboratories, Inc., Palo Alto, Calif. while luciferaseexpression vectors and luciferase gene cassettes are available from ProMega Corp. (Madison, Wis.). General methods of culturing plant tissuesare provided for example by Maki et al. “Procedures for IntroducingForeign DNA into Plants” in Methods in Plant Molecular Biology &Biotechnology, Glich et al. (Eds. pp. 67-88 CRC Press, 1993); and byPhillips et al. “Cell-Tissue Culture and In-Vitro Manipulation” in Corn& Corn Improvement, 3rd Edition Sprague et al. (Eds. pp. 345-387)American Society of Agronomy Inc. et al. 1988.

Methods of introducing desired recombinant DNA molecule into planttissue include the direct infection or co-cultivation of plant cellswith Agrobacterium tumefaciens, Horsch et al., Science, 227:1229 (1985).Descriptions of Agrobacterium vector systems and methods forAgrobacterium-mediated gene transfer provided by Gruber, et al. supra.Other useful methods include but are not limited to expression vectorsintroduced into plant tissues using a direct gene transfer method suchas microprojectile-mediated delivery, DNA injection, electroporation andthe like. More preferably expression vectors are introduced into planttissues using the biolistic microprojectile delivery orAgrobacterium-medicated transformation. Transformed plants obtained viaprotoplast transformation are also intended to be within the scope ofthis invention.

Many traits have been identified that are not regularly selected for inthe development of a new cultivar but that can be improved e.g. bybackcrossing techniques or by genetic transformation. Examples of traitstransferred to cultivar M001483 include, but are not limited to,herbicide tolerance, resistance for bacterial, fungal, or viral disease,nematode resistance, insect resistance, enhanced nutritional quality,such as oil, starch and protein content or quality, improved performancein an industrial process, altered reproductive capability, such as malesterility or male fertility, yield stability and yield enhancement.Other traits transferred to cultivar M001483 are for the production ofcommercially valuable enzymes or metabolites in plants of cultivarM001483.

Traits transferred to soybean cultivar M001483 are naturally occurringsoybean traits or are transgenic. Transgenes are directly introducedinto cultivar M001483 using genetic engineering and transformationtechniques well known in the art or described above, or are originallyintroduced into a donor, non-recurrent parent using genetic engineeringand transformation techniques and are then introgressed into cultivarM001483, for example by backcrossing. A transgene typically comprises anucleotide sequence whose expression is responsible or contributes tothe trait, under the control of a promoter capable of directing theexpression of the nucleotide sequence at the desired time in the desiredtissue or part of the plant. Constitutive, tissue-specific or induciblepromoters preferably are used. The transgene may also comprise otherregulatory elements such as for example translation enhancers ortermination signals. In a preferred embodiment, the nucleotide sequenceis the coding sequence of a gene and is transcribed and translated intoa protein. In another preferred embodiment, the nucleotide sequenceencodes an antisense RNA or a sense RNA that is not translated or onlypartially translated.

Where more than one trait are introgressed into cultivar M001483, it ispreferred that the specific genes are all located at the same genomiclocus in the donor, non-recurrent parent, preferably, in the case oftransgenes, as part of a single DNA construct integrated into thedonor's genome. Alternatively, if the genes are located at differentgenomic loci in the donor, non-recurrent parent, backcrossing allows torecover all of the morphological and physiological characteristics ofcultivar M001483 in addition to the multiple genes in the resultingsoybean cultivar.

The genes responsible for a specific, single gene trait are generallyinherited through the nucleus. Known exceptions are, e.g. the genes formale sterility, some of which are inherited cytoplasmically, but stillact as single gene traits. In a preferred embodiment, a transgene to beintrogressed into cultivar M001483 is integrated into the nuclear genomeof the donor, non-recurrent parent or the transgene is directlytransformed into the nuclear genome of cultivar M001483. In anotherpreferred embodiment, a transgene to be introgressed into cultivarM001483 is integrated into the plastid genome of the donor,non-recurrent parent or the transgene is directly transformed into theplastid genome of cultivar M001483. In a preferred embodiment, a plastidtransgene comprises one gene transcribed from a single promoter or twoor more genes transcribed from a single promoter.

A trait transferred to cultivar M001483 is for example resistance tobrown stem rot (U.S. Pat. No. 5,689,035) or resistance to cyst nematodes(U.S. Pat. No. 5,491,081), both incorporated herein by reference. In apreferred embodiment, a transgene whose expression results orcontributes to a desired trait to be transferred to cultivar M001483comprises a gene encoding an insecticidal protein, such as, for example,a crystal protein of Bacillus thuringiensis or a vegetative insecticidalprotein from Bacillus cereus, such as VIP3 (see for example Estruch etal. Nat Biotechnol (1997) 15:137-41, incorporated herein by reference).In another preferred embodiment, a transgene introgressed into cultivarM001483 comprises a herbicide tolerance gene whose expression rendersplants of cultivar M001483 tolerant to the herbicide. For example,expression of an altered acetohydroxyacid synthase (AHAS) enzyme confersupon plants tolerance to various imidazolinone or sulfonamide herbicides(U.S. Pat. No. 4,761,373, incorporated herein by reference). In anotherpreferred embodiment, a non-transgenic trait conferring tolerance toimidazolinones or sulfonylurea herbicides is introgressed into cultivarM001483. Expression of a mutant acetolactate synthase (ALS) that renderthe plants resistant to inhibition by sulfonylurea herbicides (U.S. Pat.No. 5,013,659), incorporated herein by reference. In another preferredembodiment, U.S. Pat. No. 4,975,374, incorporated herein by reference,relates to plant cells and plants containing a gene encoding a mutantglutamine synthetase (GS) resistant to inhibition by herbicides that areknown to inhibit GS, e.g. phosphinothricin and methionine sulfoximine.Also, expression of a Streptomyces bar gene encoding a phosphinothricinacetyl transferase in maize plants results in tolerance to the herbicidephosphinothricin or glufosinate (U.S. Pat. No. 5,489,520, incorporatedherein by reference). U.S. Pat. No. 5,162,602, incorporated herein byreference, discloses plants tolerant to inhibition by cyclohexanedioneand aryloxyphenoxypropanoic acid herbicides. The tolerance is conferredby an altered acetyl coenzyme A carboxylase(ACCase). U.S. Pat. No.5,554,798, incorporated herein by reference, discloses transgenicglyphosate tolerant maize plants, which tolerance is conferred by analtered 5-enolpyruvyl-3-phosphoshikimate (EPSP) synthase gene. Inanother preferred embodiment, tolerance to a protoporphyrinogen oxidaseinhibitor is achieved by expression of a tolerant protoporphyrinogenoxidase enzyme in plants (U.S. Pat. No. 5,767,373, incorporated hereinby reference). In a preferred embodiment, a transgene introgressed intocultivar M001483 comprises a gene conferring tolerance to a herbicideand at least another nucleotide sequence for another trait, such as forexample, insect resistance or tolerance to another herbicide.

Specific transgenic events introgressed into cultivar M001483 are forexample found at http://www.aphis.usda.gov/bbep/bp/not₁₃ reg.html,incorporated herein by reference, and are for example introgressed fromevents G94-1, G94-19 or G-168 with altered oil profile (applicationnumber 9700801), from phosphinothricin tolerant events W62, W98,A2704-12, A2704-21 or A5547-35 (application number 9606801) or fromglyphosate tolerant event 40-3-2 (application number 9325801).

Direct selection may be applied where the trait acts as a dominanttrait. An example of a dominant trait is herbicide tolerance. For thisselection process, the progeny of the initial cross are sprayed with theherbicide prior to the backcrossing. The spraying eliminates any plantwhich do not have the desired herbicide tolerance characteristic, andonly those plants which have the herbicide tolerance gene are used inthe subsequent backcross. This process is then repeated for theadditional backcross generations.

This invention is also directed to methods for producing a soybean plantby crossing a first parent soybean plant with a second parent soybeanplant, wherein the first or second parent soybean plant is a soybeanplant from cultivar M001483 or a plant from cultivar M001483 furthercomprising one or more specific, single gene traits. Further, both firstand second parent soybean plants may be from the cultivar M001483 orfrom cultivar M001483 further comprising one or more specific, singlegene traits. Therefore, any methods using the cultivar M001483 are partof this invention; selfing, backcrosses, hybrid breeding, and crosses topopulations. Any plants produced using cultivar M001483 or cultivarM001483 further comprising one or more specific, single gene traits as aparent are within the scope of this invention. For example, the soybeancultivar M001483 or cultivar M001483 further comprising one or morespecific, single gene traits are used in crosses with other, different,soybean plants to produce first generation (F1) soybean hybrid seeds andplants with superior characteristics. For example, a method to produce ahybrid soybean seed comprises the steps of planting, preferably inpollinating proximity, seeds of soybean cultivar M001483 or seeds ofsoybean cultivar M001483 further comprising one or more specific, singlegene traits and another soybean cultivar, cultivating the soybean plantsresulting from said seeds until said plants bear flowers, emasculatingthe plants of either one or the other soybean cultivar, inducing crosspollination to occur between said soybean cultivars and harvesting seedsproduced on said emasculated plants of the cultivar line.

As used herein, the term “plant” includes plant cells, plantprotoplasts, plant cells of tissue culture from which soybean plants canbe regenerated, plant calli, plant clumps, and plant cells that areintact in plants or parts of plants, such as pollen, flowers, seeds,pods, leaves, stems, and the like. Thus, another aspect of thisinvention is to provide for cells which upon growth and differentiationproduce the cultivar M001483.

Further reproduction of the cultivar can occur by tissue culture andregeneration. Tissue culture of various tissues of soybeans andregeneration of plants therefrom is well known and widely published.

Thus, another aspect of this invention is to provide cellswhich upon growth and differentiation produce soybean plants having thephysiological and morphological characteristics of cultivar M001483.

The seed of soybean cultivar M001483 or soybean cultivar M001483 furthercomprising one or more specific, single gene traits, the plant producedfrom the seed, the hybrid soybean plant produced from the crossing ofthe variety with any other soybean plant, hybrid seed, and various partsof the hybrid soybean plant can be utilized for human food, livestockfeed, and as a raw material in industry.

Soybean is the world's leading source of vegetable oil and protein meal.The oil extracted from soybeans is used for cooking oil, margarine, andsalad dressings. Soybean oil is composed of saturated, monounsaturatedand polyunsaturated fatty acids. It has a typical composition of 11%palmitic, 4% stearic, 25% oleic, 50% linoleic and 9% linolenic fattyacid content (“Economic Implications of Modified Soybean Traits SummaryReport”, Iowa Soybean Promotion Board & American Soybean AssociationSpecial Report 92S, May 1990. Changes in fatty acid composition forimproved oxidative stability and nutrition are constantly sought after.Industrial uses of soybean oil which is subjected to further processinginclude ingredients for paints, plastics, fibers, detergents, cosmetics,and lubricants. Soybean oil may be split, inter-esterified, sulfurized,epoxidized, polymerize, ethoxylated, or cleaved. Designing and producingsoybean oil derivatives with improved functionality, oliochemistry, is arapidly growing field. The typical mixture of triglycerides is usuallysplit and separated into pure fatty acids, which are then combined withpetroleum-derived alcohols or acids, nitrogen, sulfonates, chlorine, orwith fatty alcohols derived from fats and oils.

Soybean is also used as a food source for both animals and humans.Soybean is widely used as a source of protein for animal feeds forpoultry, swine and cattle. During processing of whole soybeans, thefibrous hull is removed and the oil is extracted. The remaining soybeanmeal is a combination of carbohydrates and approximately 50% protein.For human consumption soybean meal is made into soybean flour which isprocessed to protein concentrates used for meat extenders or specialtypet foods. Production of edible protein ingredients from soybean offersa healthy, less expensive replacement for animal protein in meats aswell as dairy-type products.
